Plenty of students, office workers, artists and nervous people chew on the ends of their pencils, and it’s usually really gross. A Brazilian chewing gum company called Gang used that tendency in order to promote their gum flavors.

The company made up 5000 pencils with gum in place of the erasers. The pencils were handed out in schools during end-of-year exams to give students something tastier and less yucky to chew on while they contemplated their test answers.
